Miller auto dark helmet

I have an older Miller auto darkening helmet that has been acting up on me. When I strike an arc it will darken at first then slowly return to standby. Sometimes it won't switch at all or just stay dark. I have already replaced the lens and the batteries twice "pricey" and had no luck. Now I am back to using a Jackson #10 fixed shade. Can the unit be repaired or is it toast.

Battery Brand..??

This may seem like an off the wall answer.... but, what brand of battery did you use??

Some models of Miller helmet have problems with some battery brands because of the battery case shape and the contact design...

Here is a thread that addresses it for the Big Window Elite... and it may very well apply to others...

I have had two BWEs die this year. I am likely to try another brand, as these are getting expensive to replace. I have had a AD that was a Praxair store brand and I think the lens is an ArcOne that has lasted for at least 15 years. I have had to modify some other hoods to accept it, as the hoods have worn out. It has a fairly big window, doesn't require that I push a button to turn it on, and does not have a replaceable battery, thus I have never changed it. I may go back to that, just liked the Miller headgear better.
Ditto what was said on the batteries.

The batteries "both sets" have been Duracell and the previous ones that always worked we're Energizer brand. I don't think there was any difference in their design and size. It is an older elite model and I never had problems when I lived I'm California but could Texas humidity have anything to do with it?

i have a miller elite helmet for the past 5 years. i too had your problem, and pulled the batteries and took a tooth pick and pried the contact prongs downward so they would make better contact with the top of the battery. this solved my problem and has been working fine ever since. i love my miller helmet
